🚀 Quick Start

Create Your First Component

1. Create folder:

   mkdir -p packages/my_package/component
   

2. Create metadata.json:

   {
     "entityType": "component",
     "description": "My components",
     "components": [{ "id": "comp_my_button", "name": "My Button" }]
   }
   

3. Create components.json:

   [
     {
       "id": "comp_my_button",
       "name": "My Button",
       "category": "form",
       "template": {
         "type": "Button",
         "props": { "variant": "{{variant}}" },
         "children": "{{label}}"
       },
       "props": { "label": "Click Me", "variant": "primary" }
     }
   ]
   

4. Use in page:

   {
     "type": "comp_my_button",
     "props": { "label": "Save" }
   }
   

5. Bootstrap:

   POST http://localhost:3000/api/bootstrap

🛠️ Key Tools & Files

Component Registry

File: /frontends/nextjs/src/lib/fakemui-registry.ts

Type-safe registry of all 151+ fakemui components:

import { FAKEMUI_REGISTRY, getFakemUIComponent } from '@/lib/fakemui-registry'

const Button = getFakemUIComponent('Button')
const formComponents = FAKEMUI_CATEGORIES['form']

JSON Renderer

File: /frontends/nextjs/src/lib/packages/json/render-json-component.tsx

Renders JSON component definitions to React:

import { renderJSONComponent } from '@/lib/packages/json/render-json-component'

export default async function Page() {
  const component = await db.components.findOne({ id })
  return renderJSONComponent(component, props)
}

Example Components

File: /packages/ui_home/component/ui-components.json

5 example components demonstrating all patterns:

• Home Button - Simple button with props
• Feature Card - Card with nested content
• Hero Section - Large hero component
• Contact Form - Form with fields
• Feature Grid - Responsive grid layout
